the activities in the cell cycle occur during a specific phases. In which phase of the cell cycle is DNA replicated?
ValentinkaMS [17]

Answer:

S phase

Explanation:

The S is short for synthesis, which means that DNA is being replicated.  This is one of the stages of interphase, when the cell is growing and getting ready to divide.  Well, this is the getting ready to divide part of interphase; the cell needs to duplicate its DNA so it has enough to divide out to daughter cells.

Why an ecosystem requires a constant input of energy
pychu [463]
The ecosystem requires a constant input of energy because energy cannot be stored. The enrgy always gets converted for supporting life in the ecosystem. Some amount of energy is also lost during this conversion. So if there is not a constant supply of energy, then the ecosystem will ultimately breakdown. In case of humans, the energy is received by consuming food. The energy of the food geets converted to the enrgy that helps a human being to complete his daily chores. So energy is being lost at every step. To regain this energy the humans have to eat food regularly. This way the humans need a constant supply of energy to survive. It is the same in the case of all living things in the ecosystem.

Explain the effects of osmosis on cells and tissues:
viva [34]

Answer:

In explanation.

Explanation:

Effect of osmosis on cells:

-Osmosis is the movement of water across a cell membrane. Cells use osmosis to maintain concentration equilibrium (the concentrations of solute inside and outside the cell are equal). Changing the amount of water allows the cells to achieve equilibrium.

Effects of osmosis on tissues:

-Red blood cells placed in a solution with a higher water concentration compared to their contents (eg pure water) will gain water by osmosis, swell up, and burst. Water will diffuse from a higher water concentration outside the cell to a lower water concentration inside the cell.

Hope this helps.
